The murder of Clarnell Strandberg

WARNING: GRAPHIC CONTENT INCLUDED BELOW

The following is from a taped interview between suspect Edmund Emil Kemper III and Investigator Michael Aluffi, held at the Santa Cruz Jail on April 28, 1973. 

Aluffi: This interview will be based around the incidents that occurred at your home last Saturday [April 21, 1973]. Is there anything that you want to tell me that led up to this incident?

Kemper: Not really.

Aluffi: Well, let’s start with the reason for it.

Kemper: That’s rather involved. The reason for it is these murders were coming to a head I felt, that I was going to be caught pretty soon for the killing of these girls, or I was going to blow up and do something very open and get myself caught, and so I did not want my mother… A long time ago I had thought about what I was going to do in the event of being caught for the crimes and the only choices I seen open is being that I could just accept it and go to jail and let my mother carry the load, and let the whole thing fall in her hands like happened last time with my grand-parents. Or, I could take her life. Well, I guess that leaves me two choices, I could either do it in the open with her knowing what was happening or I could do it when she didn’t know what was happening. Last Friday night, whatever date that was, I had decided it was the night before the killing, or the day before the killing really, I had been thinking about it for quite a while and I just started working myself up towards the act of killing her. I guess that answers the reason.

Aluffi: All right, you want to get into the actual crime?

Kemper: OK. I got home Friday night, or I got back to her home from Alameda, where I’d been working early Friday in the afternoon and I sat around the house and took care of a few business problems, you know, calling and  making a couple phone calls that were unrelated to the problem, and I called my mother at work and let her know I was in town and she told me that she was going out to a dinner, some faculty dinner or something, and she’d be home late. So, I sat around and drank some beer, watched television, stayed up as late as I could and I had wished to talk to her really, before anything had happened. It was my hopes that she would go on good terms and this was impossible because, well I guess it would be good terms because we hadn’t really argued or anything when we talked on the phone. I went to bed about midnight I guess and I woke up a couple hours later. Well, let me see, that doesn’t work out right. I think I went to bed around two and she still wasn’t home and I went to bed and went to sleep. I woke up a couple hours later, around four, and she had already come home, done whatever she does when she gets home late at night and had retired for the evening. This was after I had gone to bed around 2:00 AM Saturday morning. She was in bed, reading a book and I woke up about four o’clock in the morning, two hours after I went to sleep roughly. The lights were pretty much out in the house. I didn’t see any lights on. I hadn’t heard anything and I thought, gee, it’s four o’clock and she’s still not home. So, I got up and I walked out of my bedroom, noticed her small light was on and walked into her bedroom, just as she had taken off her glasses and turned the light off. Without her turning it back on, she commented that uh, I said oh, you’re home, and she says, you’re up, what are you doing up? I said well, I just wanted to see if you were home. I hadn’t heard anything. She said, oh I suppose you want to talk. This has happened several times before, when she’d come in late and I wanted to talk and we’d talk and then she’d go to sleep. She didn’t say it in an abusive manner, it was more or less just jive and I said no. She said well, we’ll talk in the morning. I said fine, good night. She left the light out and I walked out of the room and back to my bedroom, layed down and decided at that point, I was going to wait another hour or so, until she was asleep before it happened.

Kemper: I looked at my watch. It was about a quarter after four, something like that, and I layed there in bed thinking about it and it’s something hard to just up and do. It was the most insane of reasons for going and killing your mother. But I was pretty fixed on that issue because there were a lot of things involved. Someone just standing off on the side, watching something like that isn’t really going to see any kind of sense or rhyme or reason to anything. I had done some things and I felt that I had to carry the full weight of everything that happened. I certainly wanted for my mother a nice quiet, easy death like I guess everyone wants. The only way I saw this possible was for it to be in bed, while she was asleep. The next thing was to decide how to do it. The only possible answer to that I saw was to take a hammer and hit her with it, in her sleep, and then to cut her throat. So, I waited till about 5:15 AM, I went into the kitchen and got a hammer. We have a regular claw hammer at home, picked up my pocket knife, the same one I’d used to kill Mary Anne Pesce with, opened it up, and I carried that in my right hand and the hammer in my left, walked into the bedroom very quietly.

Kemper: She had been sound asleep. She moved around a little bit and I thought maybe she was waking up. I just waited and waited and she was just laying there. So, I approached her right side, to my right on the right side of the bed, on her side. I stood there for a couple of minutes and spent most of that day, and most of that week I suppose and most of that night, trying to get myself I guess you’d say hopped up to do something like that, thinking nothing but reasons to do it and the need to do it, trying to keep everything else out of my mind. I stood by her side for a couple of minutes I suppose and about 5:15 I struck and I hit her just above the temple on her right side of the head, the side that was up from the pillow. It was above and behind her temple on the right side of her head. I struck with a very hard blow and I believe I dropped the hammer, or I layed it down or something. Immediately after striking that blow, I looked for a reaction, and there really wasn’t one, blood started running down her face from the wound, and she was still breathing, I could hear the breathing and I heard blood running into her, I guess it was her windpipe. It was obvious I had done severe damage to her, because in other cases where I had shot people in the head, I heard the same, or it had the same effect, blood running into the breathing passages, and this all happened in a few moments.

Kemper: But after I struck, I moved her over in the bed on her back and with my right hand holding her chin up, I slashed her throat. She bled profusely all over and I guess it was an afterthought, I hadn’t really thought of it, but her being my mother, and me out doing those other things, and I knew right off if I had torn everything out in the open, and my plan which I didn’t mention earlier, had been to just, well everything’s getting to an end and I could either kill her and turn myself in or I could kill her and head out with everything I had, my arsenal. This was my choice at that time. So, I decided at that time, it’s a hell of a cliché to use, but I guess what was good for my victims was good for my mother. So, after I slashed her throat, I went ahead and slashed the rest of the way around her neck and took off her head, and I guess half as much of that was to make absolutely sure in my own mind that she was dead instantly and right then, so the whole attack took maybe, less than half a minute, possibly even as little as 20 seconds…

“I’d love to take credit for more [victims]”

Aluffi (left), Kemper (right)

The following is from a taped interview between suspect Edmund Emil Kemper III and investigator Michael Aluffi, held at the Santa Cruz Jail on April 28, 1973. 

Aluffi: Ed, you’ve admitted to the deaths of six coeds, your mother and Mrs. Hallett, are there any other homicides that you’ve committed other than your grandmother and your grandfather?

Kemper: No.

Aluffi: None whatsoever?

Kemper: None whatsoever.

Aluffi: What about in Santa Rosa?

Kemper: No. There almost was a victim there, but I guess pretty much for the same reason I didn’t kill so many others, it was a surprise pickup and quite a lovely young lady, and I just psychologically was not prepared for it. But when I was psychologically in the mood for it and everything worked out right, the person didn’t have a chance, when I knew ahead of time. 

Aluffi: But you did pick up a hitchhiker in Santa Rosa?

Kemper: Yes, the deposited her safely. She was probably 16 or 17 years old.

Aluffi: What about Los Angeles?

Kemper: No, I picked up people up and down there for the same reason, only on one occasion, two girls, and I released them at their destination and picked up one girl in Santa Barbara that was headed for Santa Cruz. But at that time, all I had was my knife and I didn’t really see an opportunity to use it. 

Aluffi: Did you ever pick up any hitchhikers in Las Vegas?

Kemper: No.

Aluffi: Have you ever been to Las Vegas?

Kemper: Yes, long, long ago and only by bus.

Aluffi: So in essence, the killings that you have admitted, those are the only ones that you’ve ever completed. 

Kemper: I’d love to take credit for more, not because I’m looking for a big score, but that I wouldn’t take credit for any that I didn’t do because, well, there’s partially the guilt factor involved and there also is the uh, well I didn’t do it, so I didn’t get any pleasure out of it or any guilt out of it and why take somebody else off the hook who did do it. Obviously, whoever did these other crimes that haven’t been solved doesn’t have too many clues against him. I’m not trying to pat anybody on the back or help anybody else get away with anything, but I figure I can’t even cop out to these crimes because they’re gonna find out that I didn’t do them and I wouldn’t be able to give you any details, not even under a lie detector test. 

Aluffi: Would you be willing to submit to a lie detector test?

Kemper: Sure, as long as it only pertained to any cases that I didn’t involve myself in. You know, there’s always questions people don’t like to sit there and have a lie detector test on concerning other parts in their lives. 

Aluffi: But you would be willing to submit to a lie detector test in reference to…

Kemper: Any unsolved murders that you might think I had something to do with, or to verify certain statements I have made concerning the crimes I did commit. 

Aluffi: You would submit to the subjects of these coeds deaths?

Kemper: Certainly.

Aluffi: Do you think you could remember anything else that might be of any consequence in these investigations?

Kemper: Not at this time I don’t.

Aluffi: Would you be willing to talk to me at a later time if you did remember something like that?

Kemper: Yes.

After 41 years in law enforcement, Aluffi retires

Michael Aluffi became homicide detective in 1972, just as the United States’ attention was about to fix on Santa Cruz, where three different serial killers, John Linley Frazier, Edmund Kemper and Herbert Mullin, would send the country into a panic.

As new detective, Aluffi had to manage the paperwork from registered firearm sales. One day, a record of sale landed on his desk for a .44 caliber magnum pistol bought by Kemper, who had a sealed juvenile record. Suspicious, Aluffi went to Kemper’s house with his partner Don Smythe to confiscate the gun until they could find out more about Kemper’s past.

“There was something about Kemper that made me uneasy when we visited his house,” Aluffi said about the 6-foot-9-inch behemoth of a man who would later be convicted of eight murders. “When he went to the trunk of his car to get the gun, Don and I instinctively put our hands on our guns and went to either side of the car. Kemper later told me that if we hadn’t been watching him so closely, he planned to kill us.”

Aluffi and Smythe’s visit to his house made Kemper nervous that the cops were closing in on him, and he killed and beheaded his mother and her best friend before fleeing. He made it to Pueblo, Colorado, before he decided to call Santa Cruz to confess. Aluffi, along with other law enforcement, was sent to Colorado to accompany the serial killer on the long ride back.

“After that I was more confident as an officer, absolutely,” Aluffi said. “I felt like there wasn’t anything I couldn’t handle at that point.”

“I’m going to murder my mother”

“I said, ‘It’s not going to happen to anymore girls. It’s gotta stay between me and my mother.’ … I said, ‘She’s gotta die, and I’ve gotta die, or girls are gonna die.’ And that’s when I decided, ‘I’m going to murder my mother.’ … I knew a week before she died I was going to kill her.”

Kemper explained in a 1984 interview that, by April 1973, he wanted to end the life of the person who he believed fueled his violent, murderous rage — Kemper’s abusive, alcoholic mother, Clarnell Strandberg, after having murdered six female students from various colleges and universities scattered along the coast of Northern California.

Kemper’s sexual achievement

Inv. Michael Aluffi:   Did you ever have any kind of a sexual achievement while you were killing them [his victims]?

KemperYes, I’m sure it’s happened before, but the only time I actually noticed an ejaculation was as I was killing Mrs. Hallett on Saturday night, as she was dying, it was a great physical effort on my part, very restraining, very difficult, much less difficult that I made it, I went into a full complete physical spasm let’s say. I just completely put myself out on it and as she died, I felt myself reaching orgasm. In the other cases, the physical effort was less. I think with the Koo girl, in the case of a suffocation, the same thing happened. But I didn’t really notice it, because I did have sex with her right after causing her to be unconscious.

Murder Capital of the World

This photo and famous Kemper quote are from the upcoming book Murder Capital of the World by Emerson Murray, which will be released in May 2021. It covers the crimes of the three active serial killers in the Santa Cruz region in California in the early 1960s, that of Edmund Kemper, Herbert Mullin and John Linley Frazier. The stories are all told through direct quotes from the murderers themselves, people from their families and those who were involved in their respective cases.

I had the chance to read an advanced copy and this book is simply terrific. Many new information and details about the Kemper case. Direct quotes from his mother, his father and his older sister are quite revealing. Many new pictures of Kemper during the trial and a never-seen-before mugshot of young Kemper. Kemper researchers will be thrilled by this book as it enriches his story quite a lot. We will do an official review when the book comes out this Spring.

Ed Kemper’s fingerprints

Just found this image of Ed Kemper’s fingerprints as they were taken on April 24, 1973, the day he surrendered himself to police after murdering his mother and her best friend, on the thisisedkemper website we previously told you about.

Kemper’s last hours of freedom are described as follows:

On the morning of April 24, 1973, Ed Kemper surrendered in Pueblo, Colorado.

He had been driving east across the country for days after committing his final murders in Santa Cruz. As he approached the Kansas border in the middle of the night, he was struck by a troubling memory from his teenage years at Atascadero State Hospital.

He turned around.

Kemper drove back the way he came and stopped at a bar in Lamar, Colorado. He had a confrontation with a local man before finishing his beer, getting into his car, and continuing west. At a phone booth in Pueblo by the side of the highway, he finally gave himself up to police.

Police looking for a gun

A few weeks before Ed Kemper murdered his mother in April 1973, Santa Cruz Sheriff’s Sergeant Michael Aluffi was instructed to confiscate a gun illegally in the possession of an Aptos man. His name was Edmund Emil Kemper III and the address was 609A Ord Drive.

The instructions had resulted from a routine bulletin from the California Department of Criminal Investigation and Identification, which said that Kemper had purchased a .44 magnum revolver in Watsonville and falsely sworn that he had never been in prison.

The notice did not give any details of Kemper’s first two murders [of his paternal grandparents], listing only court disposition of the case and his prison record.

Aluffi drove to the apartment, but found no one at home. As he was walking away from the apartment door, a yellow Ford pulled into the parking space beside his unmarked vehicle. A large, brown-haired young man and a small young blonde girl were in it. It was Kemper and his fiance.

Kemper discussed the event in his 1984 interview for the documentary “Murder – No Apparent Motive”:

Journalist: Some police department actually came to your house to pick up a handgun. 

Kemper: The sheriff’s representatives, one of the detectives was upset because he heard I had a .44 magnum pistol and was a convicted mental patient and killed. He came to take the gun away. They were staking out the wrong house across the street and I’m playing around with a car, standing next to the gun in the trunk. They come over and asked, “Excuse me, sir. Do you know who lives in this house across the street?” Well, that house was 609 Harriet. He crossed back over to this side, 609 Ord, and they were looking for me and didn’t even know that was me. Bad news. Well, at any rate, we walk in the house and have them ask my mother about this other house, and I’m saying, “Hey, which 609 are you looking for?” They said, “Are you Ed Kemper?” “Yes,” and it goes on and I needed to find out what they were looking for, the murder weapon, the .22 automatic or the .44 magnum, and I don’t want to advertise that I’ve got a whole bunch of guns. So, I made a comment just to divide between the two and I suggest, “quite a little gun, isn’t it?”

He reported, “.44 magnum, I hope so.” Okay, because that loaded .22 was under the front seat and guarantee me an arrest right on the spot and the .44 was in the trunk. I forgot that. I took them in the house. We went into my bedroom and the closet doors open and I have a high-powered rifle with a scope on it with some other stuff in the house.

You had some other stuff in the house, yes?

Yeah, I had the personal effects of the last two coeds that had been murdered about two months before, right next to the guns in the closet in a box.

Could he have seen it?

No, but when he arrested me for having all those guns and went through the closet looking to see if there were any pistols or anything else, he wouldn’t have… couldn’t have helped notice a purse, a book bag and coed ID inside of those belonging to their two latest murder victims. I back up and I say, “Oh, excuse me. I just remembered something,” and instantly he responds to what I’m saying. My hand moves, back we go outside, and he’s still thinking, “Boy, this is a really nice and helpful guy here.”

Kemper’s mother’s car

This photograph shows Ed Kemper’s mother’s car as he left it after killing her. He parked it on a different street in their neighbourhood so that people would think that she wasn’t home.

Kemper talks about it in his confessions in 1973 following his arrest: “So, I drank some beer I think that afternoon, Saturday, and was sitting around the house. I had some time during Saturday also, took the keys to my mother’s car and drove it out to an area not far from our home, but a street that I knew our family and friends wouldn’t be driving up. I parked my mother’s car there, locked it up, took the keys home and I think I left them there, I’m not sure, I may have taken them along.”

Thanks to author Emerson Murray for providing this information. He is currently writing a book on the Frazier-Mullin-Kemper crimes in Santa Cruz during the early 1970s, Murder Capital of the world, to be released in 2021.

“Good luck.”

“[Reporter Marj von B] gave me a pen that day, it was a cast aluminum ballpoint pen, and I took it back to my high-security jail cell up in Redwood City. I was really slammed down tight: a two-man cell by myself. They have a camera on me 24-hours a day. The lights are on-two sets of these four-footers-it’s bright as day 24-hours a day, and I was there for five months, and I get strip shook leaving the cell and strip shook coming back in. I brought the pen in with my legal papers, and a few months later in the middle of the trial, I smashed the pen on the floor with my boot, sharpened it-got a sharp edge on the metal-and slashed my wrist. I was bleeding all over the place. It was very messy and very exciting, and everybody was dragging me off to the hospital and I got sewed up. I got shot up with industrial strength mace. They had about a quart of it and they just gassed me with that whole thing and dragged me off to the hospital.” […]

“At one point I could see every aspect of my life, my crimes, who I was, how I really felt about things without any defensive or protective accoutrements. It was fascinating to me: I was semi-conscious-actually, I was conscious, I just couldn’t get up and move around a lot, and at the end of the two hours, I didn’t want to stop. I wanted to keep on with this. I hadn’t gotten to the crimes themselves, I was kind of oriented around other things related to my life. I asked to continue on, and the doctor didn’t want to, so I insisted. They were using an IV and shot me up with another two-hour batch of this stuff, and as soon as he was done with what he wanted to do, he got up and left.”

“He had an appointment and it had gone longer than he had planned on it so he had to leave and my lawyer had to go. So, I’m stuck with these two deputies and a registered nurse watching me until I come down off of this stuff. Well, when the doctor left, he decided to give me a shot of medicine to snap me out of this, and I asked him what it was, and he said it was Methedrine-hospital-grade speed. I’ve asked doctors since then, both medical doctors and psychiatrists, if that was an appropriate action, and they said absolutely not. They should have left me sleep it off. It is suggested that the doctor knew full well it would put me through hell. It amplified everything I was feeling, it got me really down, and for two days after that they were trying to scrape me off the ceiling-they couldn’t even talk to me. I was raving and ranting. They had to put me in a strip cell because I refused to go back to my regular cell. There was television available there. I had canteen. I had some food items, but I wouldn’t accept it.” […]

Kemper as seen in his 1991 interview with Stéphane Bourgoin.

“Under the influence of those drugs, I was seeing what I did through other people’s eyes, not through mine; as someone else would view it-pure horror-how someone with nothing to do with violence in their life would see it. It was an awful experience. Within hours of coming down off that stuff two days later, I wasn’t making comments like that, [my] defenses were back in place-they were a bit ruffled. It had been an eye-opening experience because it gave me some perspectives on my case that I would never forget-some anxieties on my case that I would never forget-and all I can give you to gauge it by is that when I went into that hospital, the nurse came out-she was the typical battle-axe, professional nurse, been on the job for twenty years… great woman… with the wheelchair, severe stern face, and she’s looking at me with razor blades.”

“I’m in the chair and she wheels me inside. Five hours later when I come out of there, she’s wheeling me out and as I’m getting into the car, I’ve got this tortured look on my face. I’ve been crying and tearing at myself. She looks at me with this very compassionate look, and she says, “Good luck.” She got a good look at what was really inside. She was already aware of the evil I was capable of and the horror that happened in the case, and then she saw a lot of my real feelings. With her knowledge of chemicals and medicine and treatments, she knew I wasn’t faking. So, from her I got good luck and she was serious. I’ve never seen her since, but ironically, the deputies that were stuck with me that day, they figured ‘he’s so outraged right now, let’s just keep him here until he calms down a bit, then we’ll take him back to jail.’”

“But I didn’t calm down. I just kept going on and on, and at one point I asked the deputies to handcuff me to the rails of the bed because I was afraid I would rip my eyes out. I was really acting up, and he had known me for a few months and he didn’t want to do that. He said, “Oh, come on Ed, that’s not really necessary.” I said, “Man, you better put them on, or I’m going to tear that goddamn gun belt off and blast you, and I might beat you to death with it.” So, he comes over with the cuffs. He was a little offended by that… so he came over with the cuffs and started putting them on my wrists and I just went through some incredible convulsion and I just yanked him clear across the bed. He had the other hand cuffed already. Zing! Off he goes, he’s hanging onto this handcuff and at that point he cuffed me up real quick and finished and I already had my leg irons at the foot of the bed and I was just yanking those rails up and down with my wrists. That was very painful with handcuffs on. We went like that for a few hours and finally they said, “We got to get him back to jail, he’s not going to change in the near future.”
